To resolve you can issue the below gem install –user-install command as shown in the below example.

After restarting LiteSpeed on a server used to develop various Ruby applications there was an error in the LSWS logs. It should be pointed out that the below error was received after straightening out a Ruby installation problem that the server had. The issue was two versions of Ruby were installed with one being installed via source and the other being installed via the Yum Package Manager on this CentOS server. Once the Ruby installation issue was resolved I thought that Rubygems and all of the proper gems had been installed though that was not the case as explained in the below resolution.

Earlier this afternoon I was working on a development server that has a web server, a PostgreSQL database, Ruby, and rubygems installed on it.

Below I describe how to find out the dependencies of a specific gem by querying the remote server but also how to download a specific gem version to see what gems are dependents.
